Looking at the source of the comment, OP only hit enter once per extension name they entered, and that's why they're showing up as if they're one long run-on sentence. @[email protected] probably didn't know that you have to double enter for things to show up on separate lines.

As far as I know, that's just always how it's been for markdown, which is what Lemmy uses. So in order to be sure that your comment looks the way you want it to, it's a good idea to use the Preview function, which Voyager thankfully also has under the 3 dots menu in the lower right.
@[email protected] also mentioned that you can put two spaces at the end of each word, and then it'll count the one enter as a proper line break.
Like this. You can also do as I did, and just put a dash in front of everything, and then it'll turn into an unordered list.
